Abstract

The present invention relates to a wireless communication system. More particularly, the present invention discloses a method and an apparatus for monitoring a downlink control channel in a wireless communication system which supports multiple carriers. According to one embodiment of the present invention, provided is a method in which user equipment that supports carrier aggregation for performing communication through the use of a plurality of component carriers monitors a downlink control channel, wherein said method comprises the steps of: receiving, from a base station, setup information for a specific component carrier from among the plurality of component carriers; starting a timer in accordance with the control signal received through the downlink control channel; and monitoring the downlink control channel through the specific component carrier and deactivating the rest of the plurality of component carriers when the timer expires.
